Strawberry jam is a seasoning that can be applied to bread or toast. In addition to a large amount of fructose, sucrose, pectin and water, strawberry jam also contains a certain amount of fruit acids, vitamins, protein, fat and iron, phosphorus, calcium and other indispensable nutrients, strawberry jam on cakes and desserts. It is widely used. Equipment selection: stainless steel sandwich pot, stainless steel colloid mill. Material selection: high-quality strawberries (good freshness, maturity, more pectin, fine meat, rich aroma), white sugar, water and so on. Production process: picking strawberries - cleaning, dicing - sandwich pot heating pre-cooking - colloid grinding and grinding - sandwich pot cooking (concentration) - cooling is completed. The steps for making strawberry jam are as follows: 1, pick strawberries: choose fresh, mature, moderately rich, with a large amount of pectin, dense meat, tough, strong flavor of strawberries. 2, cleaning, dicing treatment: clean the strawberries, cut into pieces, go to the heart, go to the fruit handle and go to the flower, after the cleaning is completed, pre-cook. 3, the sandwich pot heating pre-cooking: first heat the sandwich pot to about 60 degrees, the treated pulp is placed in the sandwich pot, plus the water that accounts for 10-20% of the weight of the pulp, boil for 10 to 20 minutes, in the strawberry pre- During the cooking process, the sandwich pot needs to be constantly stirred to soften the upper and lower layers of the fruit. The pre-cooking process of strawberry directly affects the gelation degree of the finished product. If the pre-cooking is insufficient, the pectin exuded from the strawberry pulp tissue will be less. Although the sugared and boiled, the strawberry jam will not be soft, affecting the flavor and appearance. However, it is not possible to pre-cook too much. If the pre-cooking is excessive, the pectin in the strawberry pulp is hydrolyzed in a large amount, which affects the gelling ability. 4, colloidal grinding and beating: the pre-cooked strawberry pieces are slurried with colloid mill equipment. 5, the sandwich pot boiled (concentrated): the strawberry pulp is poured into the sandwich pot and boiled, and the sugar liquid with a concentration of about 75% is added in 1 or 2 times, and the concentration is continued, and the sandwich pot needs to be continuously stirred during the concentration process. . After concentrating for 30 to 50 minutes, the thickness of the strawberry jam can be cooled when it is suitable. The strawberry jam is made in a simple way, and the finished strawberry jam needs to be placed in a clean and sealed container and cooled.
